This 15 amp SPST (single pole, single throw) switch is spring-loaded to return to the Off position (Normally Open). It is ideal for a starter switch, controlling a priming pump, or for any other momentary-on switching function.
The switch contacts are made of solid, fine silver for highest reliability. The nickel-plated toggle measures 11/16 inch long. The threaded mounting bushing measures 15/32 inch long and mounts in a 15/32 inch hole. This switch is made for us with a special "Reversed Keyway" so that it will work properly with our Red Military Switch Guard (Part No. 4429, sold separately). Mounting hardware is furnished.
This switch has solder lug terminals for the most reliable connection. We also offer a similar SPST Momentary-On Toggle Switch with Push-On Spade Terminals (Part No. 4417) for easier hookup.
